The 2009 outbreak of HINI is a new kind of influenza virus, commonly referred to as “swine flu”. It is thought to be a break of four known kinds of influenza. A virus subtype H1N1: one endedmic(流行病) in humans, one endemic in birds, and two endemic in pigs (swine). The source of the outbreak in humans is still unknown, but cases were first discovered in the U.S. and soon after in Mexico.

According to the U.S. Centers for Disease Control and Prevention(CDC),it is not yet clear how serious this new virus actually is compared with other influenza viruses, although on May 26 they stated that new cases in the U.S. have probably reached the hightest point, and most cases have so far been mild relative to “seasonal flus”. But because this is a new virus, most people will not have immunity(免疫性) to it, and illness may eventually become more severe and widspread. The H1N1 flu mainly spreads in the same way that regular “seasonal influenza” spreads through the air from coughs and sneezes or touching those infected. It cannot be transmitted from eating cooked pork or by being in close contact with pigs.

As yet there is no vaccine(疫苗) available to prevent infection although companies are in the planning stages for having one available later this year. But there is concern that the virus could vary again over the coming months, leading to a new and potentially more dangerous flu outbreak later in the year, and a vaccine that will be less effective in preventing its spread.

As of May 27, the virus had spread to more than 50 countries; however, over 80% of reported deaths have taken place in Mexico. According to the CDC, the fact that the flu’s infection activity is now monitored more closely may help explain why more flu cases than normal are being recorded in Mexico, the United States and other countries.

People have been painting pictures for at least 30,000 years. The earliest pictures were painted by people who hunted animals.They used to paint pictures of the animals they wanted to catch and kill.Pictures of this kind have been found on the walls of caves in France and Spain.No one knows why they were painted there.Perhaps the painters thought that their pictures would help them to catch these animals.Or perhaps human beings have always wanted to tell stories in pictures.

    About 5,000 years ago,the Egyptians and other people in the Near East began to use pictures as kind of writing. They drew simple pictures or signs to represent things and ideas, and also to represrnt the sounds of their language. The signs these people used became a kind of alphabet.

    The Egyptians used to record information and to tell stories by putting picture-writing and pictures together. When an important person died ,scenes and stories from his life were painted and carved on the walls of the place where he  was buried. Some of these pictures are like modern comic strip stories.It has been said that Egypt is the home of the comic strip .But , for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple.The ordinary people could not understand it.

    By the year 1,000 BC,people who lived in the area around the Mediterranean Sea had developed a simpler system of writing . The signs they used were very easy to write, and there were fewer of them than in the Egyptian system . This was because each sign , or letter, represented only one sound in their language.The Greeks developed this system and formed the letters of the Greek alphabet. The Romans copied the idea, and the Roman alphabet is now used all over the world.

   These days ,we can write down a story ,or record information, without using pictures.But we still need pictures of all kinds: drawing , photographs, signs and diagrams. We find them everywhere: in books and newspapers, in the street, and on the walls of the places where we live and work. Pictures help us to understand and remember things more easily ,and they can make a story much more interesting.
